The steel burrs will clog up and chatter a lot sooner than the courser aluminum burrs will shruggy work
I have both and as well as some very small diamond coated burrs for a much smaller hand held adjustable speed grinder like jewelers use, they all have their uses but I try not to use the wrong one on any job luck
You learn by doing work scope
Once you get the burr to start chattering in a small enclose space you may have the grinder vibrate out of your hand or break the shaft of the burr, NOT GOOD shock
